How do I make friends?

This is an easy one. Once you're logged in, you'll see +Friends on registered Local Tourist profiles. Click on that link, add an optional message, click Send, and wait for them to accept.

You can keep track of your friends, people you want to be friends with, and people who want to be friends with you by moving your mouse over "Local Tourists" on the navigation bar, then clicking on "My Relationships".
